About Day One Angels
An early-stage angel fund investing in AI founders at the very beginning — when clarity, conviction, and execution matter most.
Who we are
Day One Angels is an angel investment fund focused on backing AI-first startups at the pre-seed and seed stages. We partner with founders early — often before everything is polished — and help them build toward scalable, fundable companies.
Our approach is simple: invest early, stay involved, and support founders through the most difficult phase of company-building.
Why we exist
Too many early-stage founders raise capital without enough clarity — and too many investors write checks without providing real support.
Day One Angels was created to close that gap. We believe the strongest early-stage outcomes come from capital paired with consistent, honest, and practical guidance.
We aim to be the first institutional believer — not just a line item on a cap table.
How we invest
Stage
We invest at the pre-seed and seed stages, typically when founders are preparing for their first institutional round or extending an early raise.
Focus
Our focus is AI-first companies — including applied AI, infrastructure, data platforms, automation, and intelligent software products.
Approach
We take a high-conviction, low-noise approach: fewer investments, deeper involvement, and long-term alignment with founders.
Support and investing — intentionally connected
In addition to direct investments, we operate a founder support program designed to help early-stage teams build toward a successful raise.
Founders in the program receive pitch feedback, product guidance, and consistent check-ins as they execute. When a company reaches the right level of traction and alignment, we may invite them to formally apply for investment.
Participation in the program does not guarantee funding — but it ensures founders are building with investor-level expectations from day one.
What founders can expect
- Direct, honest feedback — not generic advice
- Clear expectations around progress and milestones
- Consistent engagement at the earliest stages
- Alignment between capital, support, and long-term outcomes
